To all whom it may concern: Be it known that I, GEORGE A. QRTWEIN, acitizen of the United States, and a resident of Maple Falls, in thecounty of Whatcom and State of Washington, have invented certain new anduseful Improvements in Automatic Shingle- Stamps, of which the followinI.is a specication.

My invention re ates to an improvement in means for marking shingles andconsists in a stamp and mechanism for operating the same, which beingattached to an ordinary shingle-packers press, will be caused toproperly mark the bunches of shingles by the operations ordinarily usedto work .said

press. e

It is now,cust mary to mark the finished bunches of shing es with abrush and stehcil. This requires the time of n operative.

IVith my improvement Aattached to a shingle-packers press, the shinglesare properly stamped by the movements of the press mechanism required tobind the bunch of shingles, no additional movements or thought of theoperator-beingrequired in order-that my stamping device may be properlyoperated..-v

Although it is now shingles, I have a machine in operation whichaccomplishes the objects of this invention as above related and forwhich 'I have applied for Letters Patent*l in the United States, filedMarch-1, 1909,-Serial No. 480,715. This machine works very well.1

Yet because of the use of a number of long; spiralV springs, somediiiicu'lty has been found in keeping these springs at the properrelated tension.

The obj ect of this invention is to im rove the stamp mechanismillustrated an described in my application above referred to and isillustrated in the accompanying sheet of drawings in which similarcharacters refer to similar parts throughout and in which Figure 1 is anend elevation of a shinglepackers press, of well known construction,showin my stamping device attached, Fig. 2 isa ront elevation of themajor portion of my gdevice with parts of the press frame to which it isattached, and Fig. 3 is an end l elevation of certain parts of my devicenot shown clearly in Fig. 1.

- More specifically: the shingle` packers press, illustrated in-Fig. 1has 'a fra e principa-lly composed of posts 33 and 3a and.

l Specification of Letters Patent. Application ledApril 30, 1909. SerialNo. 493,220.

custolmary to stencil 1 cross pieces-34, 21, and 36. A horizontal shaft29 ind's bearlngs in pillow blocks '35, only one of which is partlyshown in Figari, attached to lower cross-pieces 34. Rigrdly attached tothis shaft is lever 26,v one endlv of which is pivoted to the lower endof comtothe lower'end of link 27," the upper end' of which isv pivotedtothe lower 'end of ten'- sion bar 24. Another similar set of bars, linkand lever is situated on the other Side of the press. lever 23', rigidlyattached thereto. A bunch. of shingles 31 occupies the cribof themachine, and the shingle ties 32 are lshown' in place thereon andpressed between lu' s on -theupper .end of tensi n bars 24 lan the upperends of compressi n bars 25, in order that the bands, not shown, may besecured in place. By raising position. at 23 the bars 24 and .25 arecaused vto occupy the dotted positions at 24 and 25 respectively. Thenwhen the end gate 37 is turned down vthe completed bunch an ,be removed.TheV passing ofthe lever 23 to and from its two produces the principalmechanical movements of the press. And on these movements-the operationof my stamp depends, asl I will now explain.

.The dog 5a is rlgidly attached to sh";ft.2$) vnearits middle part, Fig.3. Next to this dog, loose on shaft 29, is retained the piece 22.aprovided with two lugs or stops 5, 5. Piece 22.a is free to revolve backand forth through an arc about .shaft 29 until one of the lugs 5 comesin contact -dog 5a. Consequently dog 5 controls the revolution -of piece22a except for the lost motion in the arc refer-red to. 011e end: offlat spiihig 22 is rigidly attached to piece 22a. O-n the right-hand endof spring 22 rests 111-n of vertical compression bar 14. Bar 14 sectionand is free to move up and down in guide 30 which is rigidly vattachedto cross beam 21a. Cross bea-m 21a is attachedA to cross beams 21 of thepress frame. The upper end of compression bar 14 terminates in the widefork 9, 9. The upper ends of fork 9, 9 furnish bearings for horizontalshaft 8% On shaft 8a are rigidly attached ears 12l` 12 of stamp box 1,said box ing markingcharactersY or type 2, Fig. The right-hand end ofshaft 8, as show-n in Patented. Jan. 25, 1910.

is preferably flat and of rectangular crosspression bar 25 and theYother` endis pivoted Shaft 29 is operated by hand '75 lever 23 to thedotted Y.

illustrated positions,

with the tail of ion gear 8, havinge teeth. ,Rigidly-attached to abracket on the rear cross beam 36 is rack havingtwo teeth. This rack isso located that it may engage pinion 8 through a portion of the upwardand downward 'movement of said pinion. On a crank arm attached to thedistant end of stamp box 1 is horizontal slide 7. A vertical ide bar 11is rigidly attached between il crossbeams 21 and 36. Guide 11 and slide7 are s'olocated that when stamp box 1y is in the position illustratedin full lines in Fig. 1 the stamp is slightlyy inclined from ahorizontal-position to lie against the lower sur.-

face of the right'handend of the bunch vof shingles 31.

But when stamp4 box 1, is inverted as shown in dotted outline atl, Fig.1, it lies in a horizontal lane. Ink box containing ink pad 19 1ssupported horizontallyon bracket 20a, rigidly attached to cross beam21a, Fig. 2, in such a place that when type box 1 is in its dottedposition at l', 'said type box may lie 'squarely thereon. The .type boxlis centrally hung on --shaft 8a and to insure that slide 7 may havepositive tendency to lie against guide 11, said ty'pc box. isover-balanced by-counterweight la. A washer of spring rubber 18 isplaced on top of guide so that fork 9 may lie on .the same when type 2makes suitable contact with ink pad -19.

The upper operative positions of my stamping apparatus are illustratedvin full lines in Fig. 1, while the -lower operative positions are shownin dotted outlines and designated by the primes of the same numeralsused in the full line positions.

To operate my stamp :assume that abunch of shingles has 'been finished'and marked, when the several parts of the press and stamp will be foundin the positions illustrat-ed in full lilies in Fig. 1. Then it isdesired to remove this bunch from the press in press.

order to pack another bunch. The end 37-is turned vdown to dottedposition 37', the hand lever 23 is raised to its dotted position at 23when, pressure being removed from the bunch-of shingles, it can be takenfrom the This movement of the hand lever, in addition to removing thepressure from the bunch of shingles, carries spring 22 to its dottedposition at 22. The downward movement of-springv 22 either permitsorforces the downward movement of compresion bar 14 and fork9. This alsocarries shaft 8 withl pinion 8 and type box 1 downward. Pinion .8-n1ovesdownward a suiiicient dis.-

. tance to permit vtype box 1 to be.revolved under the on rack 10thereby bunch of shingles, when one of its teeth comes in contact lwiththe upper tooth causing type box l to revolve about shaft 8 3 in aclock-wise direction, and carrying slide 7 out and away'from guide v11.This revolution continues until the further another bunch o f shinglesoccupies the crib of the press and it is desired -to compress the samepreparatory to affxing the bands thereto, hand lever 23 must be carriedfrom position 23 to position 23. `Because of the space between the tailof dog 5a and upper lug 5, when the several parts are in their dottedpositions, there is some downward movement of lever 23 before said dogcomes in lcontact with said lug. This permits of some pressure to bebrought on the loose bunch of shingles before the compression'rod 1-1begins lts upward movement. dien this movement beglns, fork 9,9 alsomoves upward and carries with it the several connected parts.

There is suiicient space'between the lower position of the pinions at 8and the lower tooth of rack 1Q so that the typebox 1 may be carriedupward sufficiently far above ink pad 19 to permit thel `said box .torevolvel above said pad. lVhen the pinion 8 strikes the rack -10 frombelow'the type box 1 is caused to revolve in a counter-clockwisedirection and the slide 7 is carried. away from guide 11. t-urnedthrough an angle than 180o to a position parallel with the lower side ofthe bunch of shingles under which it is located,'the pinion 8 has-passedthe upper tooth 'of rack 10 and the slide 7 has come in contact withguide 11, so that revolution ceases. The upward movement of saidtype-box, due primarily to the downward movementof hand lever 28,continues until, when the bunch of shingles 31 is brought fully underthe compression of the press, thel type 2,' freshly inked, is broughtsquarely and firmly in contact with said bunch of shingles by upwardpressure from spring 22. This invention relates onlyA to theconstruction of the stamping mechanism and is not concerned with themore general combination of said mechanism and the mech'- anism of thepress which I havemore articularly referred to in tion cited above.

Having thus described my invention, I claim,
